Abstract
The present invention concerns the use of a mixture of organic peroxides for crosslinking a polyolefin elastomer (POE), in particular intended to be used in photovoltaic applications. The invention also relates to a crosslinkable composition comprising at least one polyolefin elastomer (POE) and at least one mixture of organic peroxides. The present invention also concerns a method for preparing a material made from polyolefin elastomer (POE), preferably an encapsulating material or a sealing agent, in particular for photovoltaic cells, comprising a step of crosslinking a crosslinkable composition as defined previously.
Claims22
A mixed organic peroxide composition for use in crosslinking a polyolefin elastomer, the composition comprising:
- at least one monoperoxycarbonate conforming to the formula (I):
- wherein in formula (I) R1 represents an alkyl radical comprising a number of carbon atoms of less than or equal to 6, and R2 represents an alkyl radical, and
- at least one monoperoxycarbonate, conforming to the formula (II):
- wherein in formula (II) R1 represents an alkyl radical comprising a number of carbon atoms of greater than or equal to 7, and R2 represents an alkyl radical,
- wherein the polyolefin elastomer is a copolymer of ethylene and at least one alpha-olefin.
